1, translation APP: travel translator, GenieTalk. These two softwares are super easy to use. "Travel Translator" is an APP of Honeycomb, which contains sentences of various situations that may occur during travel. I can pronounce and translate Korean. Korean pronunciation is also very authentic, not very rigid. GenieTalk is a real-time translation software, and the translated grammar is very practical and easy to use. I just need a network. I suggest using coupons to build an egg in Han You. I can surf the internet at any time in Korea, which is very easy to use.

2, travel guide APP: buzz, travel guide, beehive specials, travel notes. They are all apps of cellular websites, which are very practical. The mobile phone can check the raiders at any time, and it can also buzz to take pictures.

3. Coupons and duty-free shops: Coupons can download the software "Play Korea", which is very practical and will have different discounts. If you can save something, you can save it. Duty-free shops are duty-free shops in Lotte and Silla. After registration, you can buy them on your mobile phone with discounts. When you leave the country and return to China, you can pick up the goods directly in the waiting hall, which is very convenient and can be taken directly to the plane without occupying luggage space.
